HEAD-GATE.

Specification of Letters Patent. Patented May 7, 1907.

' Application filed August 16, 1906. Serial No. 330,923.

To all whom, it may concern:

Be it known that 1, WILLIAM F. GARBE, a citlzen of the United States, residing at Fort Collins, in the county of Larimer and State of Colorado, have invented certain new and useful Improvements in Head-Gates; and I do declare the following to be a full, clear, and

this view it is assumed that the head gate is completely closed. Fig. 7 1s a detail view of the manipulating hand wheel. Fig. 8 is a detail view of one member of the cam clutch employed in looking the gate. Flg. 9 1s a similar view of a cam member cooperating with the member shown 1n Fig. 8. Fig. 10 is exact description of the invention, such as a top View of the structure with a hand Wheel will enable others skilled in the art to which I and the upper clutch member removed, the it appertains to make and use the same, refer- I gate stem being snown in cross section. ence being had to the accompanying draw- I The same reference characters indicate the ings, and to the letters and figures of refer- I same parts in all the views. ence marked thereon, which form a part of Let the numeral 5 designate a head gate this specification. frame whose upper portion is composed of a My invention relates generally to improvepair of separated members 6 located on each ments in gates or valves for controlling the side and connected at the top by a yoke or passage of water or other fluid through a concross piece 7 provided with a central opening duit. I through which passes the hub 8 of a hand The invention as set forth in this applicawheel9, the said hub having a threaded opention will be especially considered with reference to its use for controlling the flow of water and for this reason it is termed a head The lower part of gate, though it must be understood that the I 1.0 of the gate proper 12. the hub 8 is provided with a reduced portion 13 eXteriorly threaded to receive a nut 14 which engages the under surface of the yoke, the latter being, however, centrally recessed and provided with a concealing plate 15- riveted to the yoke as shown at 16, to prevent possible tampering with the structure. The hub of the hand wheel is therefore j ournaled in the yoke and free to rotate whereby the gate when unlocked is raised and lowered at will.

Revolubly mounted upon the top and cenconstruction may be employed in other relations.

The novel features of the invention relate to the means for locking the gate in any desired position of adjustment the means for forcing the gate or valve proper tightly against its seat upon the portion of the frame connected with the conduit, the same being accomplished through the instrumentality of rollers which engage an inclined track during the closing action of the gate whereby a wedging action takes place; and the means whereby the head gate frame is connected with the outlet extremity of the conduit. These features will all be hereinafter described in detail, reference being made to the accompanying drawingin which,

Figure 1 is a front view of the head gate oartially in section, showing the hand wheel unlocked. Fig. 2 is a side elevation of the same length showing the hand wheel unlocked. Fig. 3 is an elevation of the upper I part of the structure showing a portion of the i whose lower surface is flat and whose upper surface is provided with cam teeth adapted to engage counterpart teeth formed on the lower surface of a cooperating cam member 18 whose upper surface is provided with crown teeth 19 adapted to engage similar teeth 20 formed on the hand wheel just above and. surrounding the top of the hub. The yoke is provided with upwardly projecting lugs 21, one being located on each side there of. These lugs form sto s to prevent the rotation of the cam meml er 18 which is provided with two pairs of depending lugs 22, one lug of each pair being located on each side of a lug 21 of the yoke. These lugs 21 and 22 are outside of the cam member 17, leaving the latter to rotate. The member 17 is provided with a manipulating arm 23 threaded stem of tne gate. Fig. 4 is a vertical section taken on the line 44 Fig. 1. Fig. 5 is a cross section takenthrough the conduit on the line 5 5 Fig. 2 viewed in the direction of the arrow. Fig. 6 1s a horizontal l section taken on tne line 66 Fig. 1. In I ing through which passes the threaded stem 5 tral portion of the yoke, is a cam member 17 padlock may so arranged that when this arm 23 is mamp side Whose outer .extremity is provided with an opening through which the hasp 24 of the be passed. The structure is ulated to bring its opening into register with an o ening in an ear 26 on the frame, the mem er 18 will be raised to cause its crown teeth to mesh with the teeth 21 of the hand Wheel, thus locking the latter against rotation. It will thus be seen that the member 17 is allowed free rotary movement when its arm is unlocked, while the member 18 is allowed free vertical movement, but locked against rotation.

provided with passes. To the op 27 are attached ang e bolts 29 passed through lugs 30 and secured by nuts 31. Each of these angle flanges has an inwardly projecting member 32 located in sides 12A of the head These members 32 are inclined as extend downwardly and are engaged front of the reinforced ate 12. they by .rollers 33 carried by the head gate, the rovided with .ins 34 said rollers being which enter verticaslots forms in the sides 12A. The u per extremities of the in- 1 clined flange mem ers 32 are farthest from the plate 27, and these flange members ap-i plate as they extend down- 1 preach the said wardly. The ro ers 33 protrude forwardly beyond the members 12A and engage the'.

flange members 32 which form a track there for. As the gate is moved downwardly to the closing osition, the rollers engage the parts 32 and are allowed a limited degree of upward ,movement. wedging action whereby the gate is forced .against its seat to form a water tight joint when the gate is in the closed osition; The

portions 12A of the head gate are also provided with slots 37 in which the rollers 33 are located and through which they pro trude in front. These rollersengage the bottom of this slot in the rear as indicated by dotted lines in Fig. 4. In order to support the rollers in such a position that they will all simultaneously engage the inclined flange parts 32 during the closing movement of the gate 1. royide the slots 37 with vertically adjustable blocks 36 :upon which the rollers rest-except when the gate is closed and-during the closing movement thereof. These blocks are held in osition by screws 36A passed through the s lots 35 of the gate.

The plate 27 of the frame, is secured to the bell extremity 29A of the conduit 49, by means-of-clamping members 38 connected by bolts 39 which pass through ears 40. By means of these bolts the clamping members form a closely fitting band or ring surround- These rollers have a nut journaled head gate stem, and means interposed being the conduit in the rear of the bell. The forward part 38A of each clamping member is shouldered to fit the shoulder of the bell and is also provided with a reinforced part 3813 apertured to receive fastening bolts 41 whose heads are countersunk in the plate 27 and to whose opposite extremities are applied fastening nuts 42. By-reason of this construction the clamping members form an even or perfect bearing upon the shoulder of the bell as the nuts 42 are tightened since the rear portion of the clam s connected by the bolts 39 prevent any roc ring tendency. Without I the bolts 39 to hold the clamping members The lower part' of the head gate frame isa plate 27 having an opening. 28 registering with an opening of a conduit 49 through which the water or other fluid. osi-te sides of this plate, flanges 58 by means of in engagement with the conduit, there would be a tendency for the rear portions of the said members to leave the surface of the conduit as the nuts 42 are tightened which would result in an uneven bearing on the bell.

From the foregoing description the use and operation of my improved device will be readily understood. Assuming that the arm 23 of the cam member 17 is unlocked, the partial rotation of this member will throw the two cam members into the relative position indicated in Fig. 3 of the drawing,

whereby the member 18 is raised and its crown teeth caused to mesh with the teeth of the hand wheel. The manipulating arm23 is then in position to be locked. This adjustment is effected after the gate has been raised or lowered to the desired, degree.

It will be understood that when the parts are in the position shown in Fig. 2, the hand wheel is free to rotate whereby the gate is raised or lowered at will. As the gate is moved downwardly to the closing position the rollers carried thereby engage the front angle flanges of the head. gate frame and force the gate tightly against its seat forming a fluid tight joint as heretofore explained.
